It will be seen that the eccentric-rod may be readily adjustedlongitudinally to con trol the action of the valves of an engine and toposition the saine properly, and that the connection obviates thenecessity of removing the eccentric-rod from an engine to lengthen orshorten it. It will also be apparent that the connection is-strong an ddurable, and that the parts are rigidly held in theiradjustinent.

In a device of the class described, .the combination of al1-eccentricstrap or yoke provided with an arni or extension, an eccentric rodarranged to slide thereon to lengthen or shorten it, anda longitudinaladjusting screw mounted on the arm or extension of the yoke or strap,and connected with the eccentric rod and adapted to slide the saine onthe arm or extension and to lsecure the rod in its adjustment,substantially as described.

2. AIn a device'of the class d scribed, the combination of -a strap oryoke provided with an extension and having threaded openings at theinner and outer ends of the extension, a longitudinal adjusting screwarranged in the said threaded openings, and an eccentric rod arranged onthe extension of thestrap or yoke and having a threaded openingreceiving the adj Listing screw between the ends of the same, saideccentric rod being capable of sliding on the extension when the screwis rotated, substantially as described.

3. In a device of the class described, the combination of a strap oryoke having an eX- tension and provided therein with a recess and havinga threaded opening or socket at the inner end thereof, a lug arranged atthe outer end of the recess and having a threaded recess, and aneccentric rod arranged in said recess and adapted to slide on theextension and provided with a lug having a threaded perforationreceiving the central portion oi' a screw, substantially as described.
